Each house has many working parts which when you effect one aspect many times this will have negative or positive effects on other areas of the house. If you would have unexpected water in the basement many times the house will have mold in the basement but could have mold in the attic eventually. These 2 areas do not seem connected but are they? If you insulate your basement walls the whole house feels warmer. How could that be? Houses are a system and should be treated that way when you insulate or air seal the house to cut down on energy or comfort issues. If contractors do not understand that a house is a system. Contractors can do more harm then good.
A house we recently inspected had relative humidity of 50% or greater, has a lot of leakage to the attic. The person living in this house wanted more insulation. So they call the first contractor they see that does insulation. This contractor insulates without air sealing. This can be a problem since now there is no more heat loss and the roof deck is 20 degrees colder then it use to be. Now all the moisturefrom the house leaks into the attic. The house was 50% relative humidity not has a chance to condense since warmer air and cold surfaces with high relative humidity form perfect conditions to condensate. This is one of many exsample of a contractor causing more issues then they are solving. A much better way would be to air seal all leakage in the attic when you want to insulate. You will have much better performing insulation and peace of mind that the chances of condensation is low.
